Why can't I get KCAU 9.1 reception from Sioux City, IA? The reason may surprise you.
If you have a TV antenna and can't receive KCAU TV channel 9.1 from Sioux City, IA. the problem is likely the TV antenna not the TV station. It doesn't matter if the antenna is an indoor, attic or roof top antenna, it's likely not designed to receive the KCAU TV VHF signal.
- The KCAU signal type is VHF.
- Most antennas on the market today are designed to receive UHF signals but not VHF signals.
- Simply put, you probably bought the wrong TV antenna.
You can't receive a VHF TV signal using a UHF TV antenna.
It requires two different types of antennas to receive each signal type. The VHF portion of the antenna must be considerably larger. The UHF portion of the antenna can be much smaller in size and get the same results. To properly receive both types of signals there must be two antennas combined into a single antenna output connection. One antenna receives VHF signal and one receives UHF signal. The two antenna signals are phased together creating a single VHF and UHF signal output on the antenna.
Is the antenna truly designed to receive the KCAU channel 9.1 VHF signal?
- Does the antenna have elements protruding horizontally from the antenna?
No protruding elements, no VHF reception.
- Are the protruding elements on the antenna at least 3 feet long?
If not, poor VHF TV reception.
Indoor set top TV antenna
Your best chance at receiving the KCAU TV signal using an indoor antenna is good old fashioned rabbit ears. The extending poles (rabbit ears) are the VHF portion of the antenna. Without these elements the KCAU TV signal travels past the antenna with very little signal received as it does so.
A paper clip becomes a VHF TV antenna.
Hopefully you have learned, just because I say a paper clip is a VHF antenna, doesn't make it a VHF antenna. You should now be able to recognize antennas making false claims about VHF TV reception. Just because an antenna claims to be capable of VHF reception, doesn't make it so.
Below are two examples of excellent TV antenna design that will receive both VHF and UHF digital TV signals equally well.
Smaller antennas of similar design are available for short and medium range VHF and UHF TV reception.
